VANCOUVER, British Columbia, Sept. 08, 2026 (GLOBE NEWSWIRE) — Domestic Metals Corp. (the “Company” or “Domestic”) – (TSXV: DMCU; OTCQB: DMCUF; FSE: 03E0) is pleased to announce the commencement of the planned 9,000m diamond drill program at its Smart Creek Project in Montana (video and photos here). The program is designed to test high-grade porphyry copper style mineralization identified through the Company’s 2025–2026 exploration campaign.

The Smart Creek Copper Porphyry Project, acquired in August 2024, is a joint venture with Rio Tinto, where Rio owns 40% of the asset. The project covers 8,000 hectares and is located 50km northwest of the Butte Mine Complex (the Butte District production is credited at 24.8B pounds of copper between 1180-20041) and occupies a similar geological setting. Smart Creek is considered prospective for porphyry copper as well as copper-gold-silver enriched carbonate replacement deposits (CRD).

Rio Tinto drilled 26 of 40 permitted sites vectoring toward a porphyry centre at the Smart Creek Target where the best hole returned 109.73 meter @ 0.75% Cu, which included 89 metres of 0.97% Copper (SMCR0022; news release dated August 20, 2024). Domestic Metals’ 2025 summer field program returned 102 g/t Au with 23.1% Cu and 3,810 g/t Ag. (news release dated January 8, 2026)

Program Highlights
Article content
- Up to 9,000 meters of diamond drilling across an estimated 6-8 holes with a focus on the Smart Creek and Sunrise Mine Targets
- Program fully funded through the Company’s existing treasury
- Targets defined by IP geophysical program, surface sampling, results of historical drill program and 3D computer modeling to help vector toward main mineralized sources on the property
- First assay results are expected 6-8 weeks following the start of the drilling
- Drilling being conducted by KP Drilling of Arizona using a Borat Longyear LF-90 D diamond drill rig

“Rig availability pushed our start date back several weeks which is an unfortunate but common reality in this market. We are pleased to confirm the rig is now on site, and drilling has commenced after nearly two years of systematic exploration at Smart Creek,” said Gordon Neal, CEO and Director of Domestic Metals. “Our geologists have developed targets based on the high-grade metal sampling results and new IP data. We believe Smart Creek is highly prospective for porphyry copper as well as copper-gold-silver enriched carbonate replacement deposits. The program is designed to deliver news flow over the coming months, starting with visual observations from core and followed by assay results as they come in.”

Project Overview
Article content
After acquiring the project in August 2024, modern exploration by Domestic has focused on identifying the broader mineralized system, using a combination of:
Article content
- Detailed geological mapping and structural interpretation
- Reconnaissance mapping and sampling, Assay results at the high-priority Sunrise Target returned 4.26 g/t Au (news release dated March 3, 2025)
- 2025 summer field program. Sampling returned high grade results: 102 g/t Au with 23.1% Cu and 3,810 g/t Ag. (news release dated January 8, 2026)
- IP Geophysics with multiple new large-scale targets identified. IP chargeability features are coincident with previously established alteration footprints and high-grade sampling (news release dated January 8, 2026). Results support Domestic Metals’ geologically and geochemically based target initiatives and represent Priority 1 drill targets at the Smart Creek Project. (news release dated April 2, 2026)
- Compilation and digitization of historic drill hole and assay data
